The cobra kit includes all of the following, clutch kit Phase 2, exhaust mod, head work, jets, and cold air kit. As for the cold air kit I can tell you that it does work on my machine and when Dynoed showed HP increase from 2-4 HP and the instructions you get with it to install my grandmother could follow. For the cost it is probally the cheapest mod for the gain result.

Hauler78,
Not trying to start an argument here but I was just wondering how you figured on the dyno that redirecting the forced air into the airbox was giving you 2-4 more horsepower? Seems like the only way to tell would be to have a 70+ mph wind tunnel to dyno test in.

what was the deal with the weight on the flaot bowl trick for the exciter? I have a 1990 exciter, and both times, leaned out in mid range.

A dealer in NE Iowa came up with that one. Helps from foaming in the bowls causing midrange lean burn downs.
